Prep expert is a really amazing course, the tips are truly amazing and my instructor, Dr. Shaan patel was amazing at explaining concepts and went really in depth. They also teach strategies that are totally unique and you won't see these ANYWHERE. These tips are really gamechanging, I went from a prety average score of 1320 to 1540! A 99th percentile score. The resources are also amazing the practice tests were really realistic and helpful and were really accurate score predictors. Some of the things they teach here will not only improve your SAT score exponentially but also your life. Lot's of thanks to prepexpert.
